You 'll need to set up your own caching DNS server, these blacklists are free, but limit requests per server, and will refuse your's if you use a public DNS (or any one from an ISP,...)
Try this:
$ dig test.uribl.com.multi.uribl.com txt +short
"127.0.0.1 -> Query Refused. See http://uribl.com/refused.shtml for more information [Your DNS IP: 74.125.73.85]"
I use powerdns recursor.
apt-get install pdns-recursor
on OS X:
brew install pdnsrec
You can add it to local.cf, if your don't want the OS to use it.
dns_server 127.0.0.1
https://wiki.apache.org/spamassassin/CachingNameserver
As a sidenote:
Caching servers are very useful in your network too.
My main DNS servers are Windows (AD, your know), but those are kind of slow, and - important - they can't do real external DNS by themselves, they need a forwarding server.
If you set them up, as most do, with Google DNS of OpenDNS forwarders, they become useless for SA network tests.
So the set-up involves 2 DNS servers *
AD DNS server, with all my internal FQDN's for use in LAN, configured with a forwarder:
PDNS_REC server, configured to look back at the AD DNS to resolve internal domains. Anything else, it gets directly form the interwebs.
Kind of a Look-At-Aach-Other-DNS, works great.
Bonus1
SA can use the PDNS_REC to do network tests
Bonus2
Any other client in your LAN can use it too, to enjoy blazing fast DNS
* (actually 4 DNS servers, 2 of each...)
